PC on 2 Gold Shadow Blades

I can either mod one of my shadow blades to this...
15-22 (req 13)
15^50
20/19
+30

or

15-22 (req 10)
15 (enchanted)
barbed
+30

the mod of course is the +30 but i need to know which would be worth more so i know which to put it one, please help me!

**BUMP**
Plz i really need the PC

i would just say since 15^50 shadow blade is req 13... it would be kinda better off if u just sold the +30hp by it self then with the sword...dont really think people want shadow blades these days :/
hope that helps

I'd salvage both for +30HP mods yeah.
